Bromothymol Blue, 0.04% Solution 60ml Dropper Bottle

I'm no chemist, but this worked exactly like I expected/needed. I am using it in a drop based titration test (I think that's the correct term) that I learned how to do over at troublefreepool.com to test my pool water for borates after I added borax.

It's ok!

Perfect! Writing review a lot later because I finally put it to good use. I used it for a titration assessment! Does the color change from blue to green to yellow!

I used this product for a science project. It worked fine for me. I have no complaints.

Experiments designed to measure co2 increases in water, which are timely considering greenhouse gas concerns, can use bromothymol blue to effectively demonstrate it. I don't know of a better way.

Shipped quickly. Much needed supply for my daughters 9th grade Biology class,thankful to have found it.

Did everything I thought it would. The students loved the experiment!

Used this for a science experiment. Kids loved it!
